Proved that `(2)/(3)times[(-6)/(7)times(4)/(5)]=[(2)/(3)times(4)/(5)]times((-6)/(7))`

(2)/(5)times(-(3)/(7))-(1)/(6)times(3)/(2)+(1)/(14)times(2)/(5)

(2)/(5)times((-3)/(7))-(1)/(6)times(3)/(2)+(1)/(14)times(2)/(5)

((-4)/(3))times(1)/(2)+((-4)/(3))times((-7)/(5))

-(2)/(3)times(3)/(5)+(5)/(2)-(3)/(5)times(7)/(6)

solve it : (ii) (-3)/(5)times(-3)/(5)times(-3)/(5)times(-3)/(5) (iii) (-9)/(2)times(4)/(2)times(-4)/(2)times(-4)/(2)times(-4)/(2)times(-4)/(2) (iv) (-5)/(3)times(-5)/(3)times(-5)/(3)times(-5)/(3) (v) (-6)/(2)times(-6)/(2)times(-6)/(2)times(-6)/(2)times(-6)/(2)

(9)/(2)-:(7)/(5)times(4)/(6)-:(2)/(3)

(6^(3)times7^(4)times8^(5))/(4^(3)times9^(2)times16)

Evaluate : ((6)/(7))^(2)times((6)/(5))^(-3)times((7)/(5))^(2)

( (5)/(6)-:(6)/(7)times(6)/(7)-(8)/(9)-:1(3)/(5)+(3)/(4)times3(1)/(3)
